ST1117 Datasheet | Semtron

DESCRIPTION The ST1117 is a positive low dropout voltage regulators with 1A output current capability. In order to obtain lower dropout voltage and fast transient response, which is critical for low voltage application. The ST1117 has been optimized. The device is available in an adjustable version and fixed output voltage of 1.8V, 2.5V, 3.3V and 5V. Dropout voltage is guaranteed at a maximum of 1.3V at 1A. Current limit is trimmed to ensure specified output current and controlled short circuit current. On-chip thermal limiting provides protection against any bination of overload that would creat excessive junction temperatures. The ST1117 is aviliable in the SOT-223 and surface mount packages. 1A Low Dropout Positive Regulator - FEATURE - Low Dropout Performance - Ajustable or Fixed Output - Over-temperature and Over-current Protection - Current Limiting and Thermal Protection - Output Current of 1A - Rugged 2KV ESD withstand capability - Full Ro HS pliance - APPLICATIONS - Battery Chargers. - Post Regulator for Switching Power Supply - Low Voltage Logic Suppliers - High Efficiency Linear Regulators - Motherboard Clock Supplies ST1117XXA-TRG ROHS pliant This is Halogen Free - PIN CONFIGURATION VIN VOUT GND/ADJ SOT-223 Top View - PART NUMBER INFORMATION ST 1117 XX A - TR G a b cd ef a : pany name. b : Product Serial number. c : Voltage Code.
